To all whom t may concern:`

Be it known that l, ALBERT Pl WoR'rHING- TON, a citizen of the United States, residing at Los Angeles, in the county of `Los Angeles and State of California, haveinvented certain new and useful Improvements in Grip Hangers, of which the following is a specification.

This invention relatesto pumpingapparatus, and relates more particularly to grip hangers. i Y

The aims of this invention include vthe provision of a grip hanger of durable and sturdy construction for pivotally `supporting suspension-means for sucker rodsor the like, and a hanger which is adapted to function with a minimum of friction and wear. Another objectof this invention isvto provide a grip hanger which may readily be secured on a walking beam against accidental'displacement,l and a hanger Sodesigned that the rod suspension means mayreadily and easily be mounted on "the hanger or be removed therefrom. Another object of this invention is to provide a grip hanger arranged to avoid harmful torsional, tensional and crystallizing strains. Other objects of this invention will be in part obvious and in part pointed out hereinafter.

It has heretofore been proposed to provide a hanger having a stem pivotally supported at the top on the upper side of a walking beam and having at its lower end, considerably below the beam, a head for supporting the rod suspension means. Such construction has been found to be fr agile and subject under Vusage to torsional, tensional and crystallizing strains in consequence whereof the stem is apt to break and the hanger rendered useless.

In accordance with my invention, instead of suspending the supporting head for the rod suspension means from the end of ai def pending rod, l mount the supporting head directly upon and in pivotal anti-frictional association with a frame placed on the walk-` ing beam. The designis such that the cable, rope, or the like, of the rod supporting means passes over the head so as to bear downwardly thereon from above, thus tending to eliminate all tortional, tensional and crystallizingstrains upon the hanger, while at the same time permitting with ease and freedom the desired pivoting of the rod suspension means with respect to the beam.

In o-rder that a clearer understanding of i kmy invention may belhad, attention is hereby directed to the accompanying drawings, forming a part of this application and illustrating one possible embodimentV of m` invention. Referring to thev drawings, Big. l

-is an end plan view of a hanger embodying my invention mounted on the end of a walkingbeam, with the cable (shown in fragfA ment) ofrod suspension means mounted on the hanger, Fig. 2 isfa vertical sectional view `taken on the line 2-2 of Fig. 1; and Fig. 3 is a top plan view .o-fll ig. 1. Similar reference characters `refer to similar parts `throughout the several views ofthe draw# in s. p y

teferring to the drawings, the'hanger includesy a frame 1, preferably an integral,

`sturdy casting, having a base 2 arranged to rest substantially upon thetop of a walking beam 3 of pumping apparatus, Hor the like,

and to which it may be secured by bolts or screws l. Arms or brackets 5 extend upwardly from base2, meeting at a reenforced portion 6, the upper surface ofwhich is indented to form a curved bearing surface '7 having an upwardly extending sto flange 8, at each end. For pivotal association with frame 1 l provide another hanger member 9, preferably semi-circular in shape, and of sturdy and durable construction, preferably being a meta-l casting; this member 9 having a peripheral rope or cable engagin groove 10 and a bearing surface 11, adapted to seat upon bearing 7 of the frame l; and also havinga recess 12 at each end of the bearing surface adapted to receive and interlock with one of the flanges 8 of the frame 1. Preferably, member 9 is provided with a cross-brace portion or member 13 which extends through an opening 14.- provided centrally in frame l.

When the parts have been assembled to gether in the above manner and the walking beam is operated, member 9 will pivot freely on frame 1 while moving the cable 15 of the rod supporting means up and down. Oil grooves 16 may be provided in bearing 7 to harbor a lubricant and to reduce friction. It is apparent that any downward pull of the cable 15 will be transmitted downwardly upon member 9 and also downwardly upon frame 1 and thereby upon the walking beam, and that no harmful torsional nor tensional strains, nor strains which would tend to create crystallization or breakage of the parts will be present. Meanwhile `like fin the groove provided therefor. The

cable or the like may be removed as readily and easily.

, embodiments of this invention may be made without departing from the scope jthereof, itis intended thatl the matter contained in `the A*above :description 'orjshownfin the ac-` cmpanying drawings be interpreted as illustrativefand not ina limitingpsense.. y t .,What I claim is y y 1 e e l. AIn a vdevice of the., character described, in combination, a frame adapted to' rest upon a walking beam, a cablesupporting member v,pivotallymounted on said frame, a"b earing surface `on said member engaging with a bearing surfaceon said frame, and inter- V flocking recesses and flanges on said frame andmember preventing relativelateral displacementof said frame and member. y

2'. In a deyice of the character described, in combination, a frame adapted to rest 4 As manychanges may be `made in'vthey above construction andjas many differenti upon the upper face of a walking beam, and t having, abearing.surface disposed over said beam, a hanger member having a bearing surface engaging said bearing surface of said frame whereby said member is pivot- Vally supported upon said frame, and a cable groove on said member disposed over said bei;1119;4 surfaces, whereby downward pull exerted by said cable on said member is transmitted downwardly upon said frame and said walking beam from above.

3. 'Inadevice of the character described, in" combination, a frame having a base adapted to rest" upon the upper face of a walking beam, and arms extending up- 4wardl-yj from said base, meeting at a rel enforced Vportion over said base, an upwardly .open semi-circular bearing surface on said i'ieenforced'portion, a'hanger member hav- !*ing a bearing surface pivotally engaging said frame bearing surface, said member fha-ving a semi-circular grooved portion for receiving.v a ,cable disposed peripherally thereon and `extending over said bearing surfaces, vand a `brace portion on said member extending through an 'opening in said frame between said arms.
